Question: A man puts on a clean shirt every night before bed. On the first nigh he puts on a blue shirt. He than sleeps for 5 hours. Every one hour more he sleeps than the night before he put on a different color shirt the next night according to this scale: blue, black, red, green, white, pink, orange, brown, purple, yellow, grey, neon green, tan, and teal. Every one hour less he sleeps than the last night he put on a different color shirt the next night going backwards on his scale. If he were to wear a blue shirt because he slept more hours than the last night he does. If it was because he slept less hours than the night before he skips it and wears a teal shirt instead. If he goes backwards on the scale and goes to blue but would not wear a blue shirt he still counts blue in his going backwards on his scale. The second night the man wears a blue shirt because he did not sleep any more or less hours than the last night. The man sleeps for six hours that night. The next night he sleeps for five hours. Night number four he sleeps for eight hours. The next night he sleeps for seven hours. The next night he sleeps so well he sleeps for 11 hours. Night number seven he stays up so late he only sleeps for four hours. The next night he is so tired he sleeps for eight hours. The next night he sleeps for eight hours again. Night number ten he sleeps for 14 hours because he is sick. Since he slept so long the last night he only sleeps for seven hours. The next night he is a little bit tired so he sleeps for eight hours. The night after that he had to do so much work he only slept five hours. The next night at work they let him out early and he slept for nine hours. The next night he slept for eight hours. And the last night the man did he slept for ten hours. The next night he put on a different color shirt according to his scale, but the next night he randomly picked a shirt. At what night will the man wear a blue shirt again?

Question: A Japanese ship was sailing in the Pacific Ocean. The Japanese captain of the ship put his diamond chain and Rolex watch on a shelf, went to get a shower and returned ten minutes later. Now listen carefully, as I will only tell it once: When he returned, both the chain and the watch were missing!! He called the crew of his ship together. There were four of them.
A British guy was the cook of the ship. The captain asked him: "Where were you the last ten minutes?" And the cook answered "I was in the cold storage room to select the meat for lunch".
A Sri Lankan was the house keeping guy. The captain repeated his question to him, and learnt that the Sri Lankan was at the top of the ship correcting the flag which had been put upside down.
An Indian guy was the engineer maintaining the ship. Same question, and the Indian told that the he was in the generator room checking the generator.
A French guy also served on the house keeping crew. Same question, and the French told that he was sleeping after the night shift.
Within ten seconds the smart captain caught the thief.
Who was the thief? How did the captain find him?

Question: Four men walk into the desert. Suddenly all four are simultaneously knocked out. They awake buried to their heads in the sand unable to look anywhere but straight ahead. They are positioned so that each man sees another's head before him. However between the first and second man there is a separating wall. So the first man sees only desert. The second man sees only wall. The third man sees another's head and a wall. The fourth man sees two heads and a wall. On top of each mans head is a hat. The underside of each cap is black, but the outside of each cap is either blue or white. Before any of the men can speak, their captors tell them if they speak, they die. However, if any of them can guess the color of their cap on the first try they go free. The captors tell them that there are two blue caps and two white caps. Being an omniscient observer of the situation, we know that the order of the caps are: blue, white, blue, white. So knowing the perspective of each man in the sand, and that they can only see the color of caps/wall/desert in front of them, which of the four men knows for certain the color of his own cap. More importantly: why?

Answer: The third man. This is because he knows there are only two of each color cap. If the man behind him (the fourth man) saw two caps that were the same color in front of him, he would know that his own must be the opposite. However, because the caps alternate in color. The fourth man has only a 50% chance of getting his hat color correct, so therefore he stays quiet. The third man realizes that the fourth man is quiet because he must not see two caps of the same color in front of him, otherwise the fourth man would say the opposite of the caps in front of him. Therefore, the third man presumes his own cap must be the opposite of the mans in front of him, and his presumption is correct. Under this same logic, after the third man speaks his color hat, the second man, even though he sees only wall, would be the next to go free, because he knows his cap must be the opposite of whichever color the third mans cap was.

Question: A married couple went to the hospital to have theit baby delivered. Upon their arrival, the doctor said he had invented a new machine that would transfer a portion of the mother's labor pain to the baby's father. He was asked if they were willing to try it out. They were both very much in favor of it. The doctor set the pain transfer to 10% for starters, explaining that even 10% was probably more pain than the father had ever experienced before. However, as the labor progressed, the husband felt fine and asked the doctor to go ahead and kick it up a notch. The doctor then adjusted the machine to 20% pain transfer. The husband was still feeling fine. The doctor checked the husband's blood pressure and was amazed at how well he was doing. At this point, they decided to try out for 50%. The husband continued to feel quite well. Since the pain transfer was obviously helping out the wife considerably, the husband encouraged the doctor to transfer all the pain to him. The wife delivered a healthy baby with virtually no pain. She and her husband were ecstatic. When they got home, the mailman was dead on the porch.

Question: There are 5 houses painted 5 different colors. In each house lives a person with a different nationality. These 5 people each drink a certain type of beverage, smoke a certain brand of cigar, and keep a certain pet.

Answer: The German. It's easiest to solve this riddle by creating a grid organized by order of the houses, you can then fill in the house number of the Norwegian, the person who drinks milk, and the blue house:

House #

These facts can all also be determined from the clues:

Brit - Red House
Swede - Dogs

Pall Mall - Birds
Yellow House - Dunhill
Blue-masters - Beer
German - Prince
Green House is to left of the White House
Blends is next to Cats

With this information these facts can be determined:

House 3 cannot be green because whoever lives there drinks milk and not coffee.

House 4 must be green since the green house needs a white house to its right.

House one cannot be red because the Brit doesn't live there.

This info leads to a single color order:
